Wrong soil mix
Using the wrong soil mix can have adverse effects on your string of pearls.
The string of pearls prefers a well-draining soil that allows excess water to drain out of the system.
If you are using the wrong soil mix, it will retain moisture, and the plant will sit on water for too long.
Even if you are giving the plant the right amount of water, using the wrong soil mix will create a similar environment to overwatering.
The roots will get affected, and the plant will not absorb enough water or nutrients from the soil. Thus, the plant will become weak, and the leaves will turn brown.
Solution: You can use a cactus mix or succulent mix that is available in the market. Or create the right soil mix that is well-draining and allows airflow in between the roots.

The string of pearls doesn’t thrive in direct sunlight. If you place your plant under direct sunlight for long, it will develop problems, one of which is brown leaves.
The string of pearls can tolerate the direct morning sunlight, but it needs indirect sunlight for the rest of the day.
If you expose your string of pearls to direct sunlight, the plant will become dry, and the leaves will get scorched, due to which the leaves will turn brown or get discolored.
If you see brown tips on your string of pearls, it might be a reason for leaf burn.
Solution: If you have a sunburnt string of pearls, you need to prune the brown leaves as the damaged leaves will not become healthy anymore.
It is best to place the plant a few feet away from the window if it gets direct sunlight. You can use curtains or blinds to filter the light.

The string of pearls has low water requirements as it is drought-resistant succulents that can go long without water.
However, you can’t ignore it entirely and stop watering it. That will make the plant under-watered, dehydrated and dry.
When the string of pearls becomes dehydrated, the leaves show signs through brown tips.
If you don’t have a watering schedule, you will likely underwater your string of pearls.
Solution: Try to follow a watering regime so that you don’t miss watering the plant. You need to check the moisture of the soil before watering the string of pearls.
You can water the string of pearls once a week during the growing season and once every two to three weeks during the dormant period.
Fertilization is essential for fast growth in your string of pearls. However, these succulents don’t need much fertilizer.
Fertilizers help to boost the growth of the string of pearls. If you give excess fertilizers to your plant, it will start showing signs such as wilting, drooping leaves, and brown tips on the leaves.
Over-fertilization happens when you give fertilizers to your plant very often and if you use a very strong fertilizer.
Solution: The string of pearls is a light feeder, so you need to use a diluted liquid fertilizer with an NPK ratio of 10:10:10.
You can give fertilizer to the plant once or twice during the growing season and skip fertilizing during the winter season.
If you follow these, you will not have an over-fertilized string of pearls.
If you have an over-fertilized plant, you need to place the plant under running water and wash it. Do this three to four times to remove the excess fertilizer.
If the over-fertilization is extreme, you need to repot the plant.
After the plant recovers and the excess fertilizer is removed, you need to reduce the fertilizing and give it only what it needs.

Solution: If your tap water has too much chlorine in it, you can switch and start giving rainwater or filtered water to your string of pearls.
If you don’t have the option to switch, you can keep the water outside and let the chlorine evaporate overnight, and then you can give that water to your string of pearls.
Pests such as aphids or mealybugs can infest your string of pearls. These pests suck the nutrition out of the plant and make them weak.

Give your plant a good shower to remove as many pests as possible. Don’t use freezing water as that can stress the plant, and be gentle while showering the plant.
You can start using organic remedies such as spraying neem oil solution on your plant.
You can get pesticides from the market but make sure that it doesn’t contain any harmful chemicals.
Spray any of these for at least 14 days to get rid of all pests and eggs. Don’t go overboard, as too much pesticide can damage the plant. Prune the brown leaves so that the plant can focus its energy on recovering and growing healthy leaves.
